I came across this article about the future of Yellowstone’s
trout. After taking comments from the public, it looks like the
Park Service has a come up with a draft plan for future trout
management. Seems pretty reasonable to me (haven’t waded
through the details though).
Lake trout have become a huge problem in the park and
hopefully these recommendations will help reduce their
numbers, allowing the native cutthroat trout population to
rebound. Also, reintroducing native cutthroat and grayling to
historical waters makes sense, although it’s interesting that
the Madison, lower Firehole and Gibbon rivers wouldn’t be
included. Historically, these waters contained native cutthroat
trout and grayling, while no fish resided in the upper Firehole
(above the falls). I imagine that people wouldn’t want to see
such a world class brown and rainbow fishery destroyed
(Selfishly, I don’t know that I would). Plus, I don’t even know
if it would be possible, for the brown and rainbows have been
residing in those waters for close to 100 years now, making
them full fledged Yellowstone residents.
If you’re interested in Yellowstone and its fishing history,
Ecology, History and Angling in the Park by John D.
Varley and Paul Schullery, is a great book to read.
